Abstract: ABSTRACT        HYDROGEN PEROXIDE COMPOSITIONS       The effectiveness of hydrogen peroxide for bleaching and disinfecting at ambient to hand hot temperatures can be enhanced by reaction with a peracid generator (activator), but the provision of storage stable concentrated aqueous liquid premixes of hydrogen peroxide and activator presents many problems arising from the physical and chemical properties of the components.      The present invention provides aqueous acidic emulsions of hydrogen peroxide and enol esters, preferably at a pH of 2 to 5 and containing a slight excess of hydrogen peroxide over an equivalent mole ratio to enol ester activator of 1:1.      The concentrations of the components of some preferred emulsions are selected in the ranges of  3 to 20% hydrogen peroxide, 30 to 85% water, 10 to 30% enol ester (%s by weight based upon the emulsion) and from 10 to 70% by weight based on the enol ester of emulsifiers.      In preferred compositions, the activator is selected from vinyl or isopropenyl or but-1-enyl or cyclohex-1-enyl acetate or benzoate and divinyl adipate or phthalate, and 1,5-diacetoxypenta-1,4-diene.      The compositions can be used as such or upon dilution with aqueous media and in conjunction with detergent compositions, and for cleaning and disinfecting absorbent or non-absorbent materials.

Abstract: ABSTRACT     A  floating  semisubmersible  off-shore  drilling platform  or the  like  comprises  an  upper  working  level  portion  and  a lower pontoon portion. When the platform is transported from one place to another, it floats on the pontoon portion, but when it is working as a stationary unit in open water, it is submerged  deeper,  so  that  the  pontoon  portion  is  at  a considerable  distance  below  the  water  surface  and  the working level portion is at a considerable distance above the water surface. The platform is adapted to withstand ice pressure from ice occurring in the ambient water by giving the  pontoon  portion  of  the  platform  a  form particularly advantageous  in  ice  conditions.  When  ice  occurs,   the platform  is  lifted  to  such  a position,  that  its  pontoon portion comes to float at the water surface level.

Abstract: BAND BUFFER DISPLAY SYSTEM                         Abstract Pixel representations for each of a plurality of superimposed (or splitscreen) display portions are accumulated in a band buffer prior to being transferred to the display.  The actual pixel representations are made available to the band buffer from an image memory, with addresses provided by a display list memory.            This system minimizes the need for buffering and high speed storage to service the video, by addressing first the display list memory, then in turn using the content of the display list memory to address the image storage, and then in turn using the content of the image storage as the actual pixel representations for accumulation in the band buffer.  Two band buffers operate alternatively.  The current band buffer is feeding a band of pixel representations to the video shift register while the next band buffer is accumulating the pixel representations of the subsequent video display band.            The band buffer accumulates actual pixel repre-sentations equivalent to the related band of the display.  The pixel representations sent to the band buffer from image memory are gated by controls which ensure that the proper pixel prevails in the case of a composite display made up of a primary display with a secondary display which might have higher priority, as, for example, a text announcement superimposed over a normal entertainment program image.

Abstract: ABSTRACT OF THE DISCLOSURE            The acoustic measuring device to examine the permeability and the fracturing of rock in the formation penetrated by a bore-hole consists of a logging sonde, immersed into a borehole fluid (mud) and moveble along the borehole axis. The sonde contains a pulse-emitting transmitter and a receiver recording the resulting echo signals. In order to record the geophysically important echo waves undisturbed by secondary signals, the effective spacing between transmitter and receiver in the sonde is smaller than half a wave length in the mud of the emitted signal. It concerns a reflection configuration comprising, essentially, of axial oscillators, which have a broad frequency band, but work, preferentially, in the lower acoustic frequency range. The recording time of the recorded sonograms (micro-seismograms) measures up to about one second.

Abstract: ABSTRACT Apparatus and method for processing a raster scan video signal representing an image and detecting the outline of one or more objects in the image represented by the video signal. The steps of the method include encoding the raster scan video signal as a sequence of binary pixel values. For each of a plurality of the pixels the following steps are performed. It is detected when the binary pixel values representing the pixel and a horizontally adjacent pixel are distinct. It is also detected when both (a) the binary pixel values representing the pixel and a vertically adjacent pixel are distinct, and (b) the binary pixel values representing a pixel horizontally adjacent to said pixel and a pixel vertically adjacent thereto are distinct. The position of the pixel is reported when either of the detecting steps detects distinct binary pixel values. The second detecting step automatically eliminates redundant pixel reporting by eliminating the reporting of double diagonal pixels.
